When Do You Require Structural Calculations?
Any home extension or loft conversion will require structural calculations. If you are carrying out an extensive home refurbishment that involves removing load bearing walls or chimney breasts, you will also need them.
Who Arranges Structural Calculations?
If you already know a good engineer then you can arrange this for yourself, but usually, the engineer works hand in hand with the architect or surveyor. They work together to ensure the specification works from an aesthetic & practical point of view.
Who Pays For Structural Calculations?
The client will need to cover the cost of this. It’s difficult to give an accurate price until the engineer has had sight of the drawings, as usually the cost is based on time or the number of steel beams requiring calculation. For standard home extensions and loft conversions costs may range from £500 to £1500.
